Re: "off and running"

: : I would like to know the exact meaning of this expresstion, I could not find it in dict.

: : my context:
: : "However, the minute I'd recover, I was off and running again". (she means to her speaking tours around USA).

: : Thank you so much

: In a horserace, the announcer says "And they're off," meaning that the race has begun or is underway and the horses are running. "Off and running" in this context means that she is again busy being back in the routine of her speaking tour.
